摘要

The two primary challenges in collecting and transporting high-paraffin and heavy oils are the deposition and accumulation of paraffins on pipeline walls and the high viscous friction forces. These issues increase hydraulic resistance and energy consumption while also compromising the reliability of pipeline systems. The task of increasing fluidity and ensuring the stability of the flow of high-viscosity oils becomes much more complicated when operating temperatures decrease. This research introduces a concept for ensuring flow stability and enhancing the fluidity of field collection and transport systems for highly paraffinic and heavy oils. The approach utilizes multiple methods, including the use of lubricating agents of pipeline walls to reduce laminar viscous friction forces and the use of agents to reduce the hydraulic resistance of pipes in the form of anti-turbulent polymer additives to quench turbulent pulsations in the boundary area and the core of the flow. Additionally, the paper presents the synergistic effects achieved through the combined use of these various methods.
